Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522976, here are decompositions:

  • 103 + 31522873 = 31522976
  • 229 + 31522747 = 31522976
  • 283 + 31522693 = 31522976
  • 307 + 31522669 = 31522976
  • 313 + 31522663 = 31522976
  • 379 + 31522597 = 31522976
  • 613 + 31522363 = 31522976
  • 619 + 31522357 = 31522976

Showing the first eight; more decompositions exist.
